Answer / chobe bapu

it is the extra ammountof air which is require for the
combustion of fuel in an engine because mixture of air and
fuel is not homogenous.

Answer / ahmed el- wakeel

In combustion there are two types of air
1- Theoretical air :- the min amount of air that supplies
enough oxygen for complete combustion. The mixture in this
case is called stoichiometric.
2- Actual air:-is more than the theoretical air by the
value of excess air.
So excess air is the amount of air supplied over or above
the theoretical air.
EX. 150% theoretica air means that the actual air supplied
for combustion is 1.5 times the theoretical air. Also means
that there is 50% excess air and it also can be expressed
in terms of "excess air factor"=1.5
